Title: Light transmitting plate having glare shielding function
Inventor: OTANI YOICHI
IPC: G09F9/00
Filed: 1986-02-28
Abstract: PURPOSE:To control the diffusion of light guided into a visual field and to improve visibility by forming a fine rugged part at least on a part of a field through which reflected light reflected by a rising wall surface of a saw tooth projecting part or a rising wall surface on a light transmitting plate is guided is guided into the visual field. CONSTITUTION:Since the reflected light of external light which is reflected by the surface side of a light transmitting plane 1 is reflected by the light transmitting plane 3 of the saw tooth projecting part 5 is guided to the outside of the visual field in a direction other than the visual direction, the visivility is improved. Even if light irradiated from the surface side of the light transmitting plane 1 or light irradiated from the back side of the light transmitting plate 1, e.g. light irradiated from an internal light source arranged in a display device such as an indicator, is made incident onto the medium of the light transmitting plate 1 and a part of the incident onto the medium of the light transmitting plate 1 and a part of the incident light 6 irradiates the rising wall surface 4 of the saw tooth projecting part 5, the irradiation light 6 is dispersed by the fine rugged part 7 formed on the rising wall surface 4. The rising wall surface 4 can be prevented from inconvenience such as partial glaring emission.

Abstract: PURPOSE:To prevent the displacement of a resist from the surface of a metal film and the coming-off of the resist by removing an oxide film formed on the surface of the film with alkaline solution, and then coating it with the resist. CONSTITUTION:An aluminum metal film 2 is formed on a semiconductor substrate 1.

Abstract: PURPOSE:To obtain extremely stable gains and to accurately measure radiation by preventing light from entering an amplifier. CONSTITUTION:When radiation enters a semiconductor radiation detecting element 1, a pair of an electron and a positive hole are generated and led out of an electrode as a charge pulse. Then the pulse output from the electrode 2 is passed through a signal line 4 and amplified by an amplifier 5. Here, a signal line 4 is made as short as possible, the semiconductor amplifying element of the amplifier 5 has its unmolded silicon substrate exposed, and the amplifier 5 is charged in a light shield body 6 of ceramic, etc. Consequently, light is cut off and never incident on the amplifier 5, whose gain never varies owing to the incidence of the light, so that the stable gain is obtained.

Abstract: PURPOSE:To prevent the generation of the nonuniformity of the concentration of toner in the axial direction of a sleeve, even if the quantity of the toner carried away from a doctor blade is made uneven by providing the grooves of depth smaller than the grain diameter of magnetic toner on a sleeve surface. CONSTITUTION:An image carrier 1 is rotated in the direction of the arrow A and an electrostatic charge image by S electrification and an exposure is formed on the surface of the carrier 1. The sleeve 2 is freely rotatably arranged opposite to the image carrier 1 and a developing region C is formed between the image carrier 1 and the sleeve 2. On the surface of the sleeve, plural grooves are consecutively formed at a prescribed interval in the axial direction, so as to obtain >=0.5mum depth smaller than the grain diameter of the magnetic toner. These grooves are formed on the surface of the sleeve 2 to prevent the irregularities in the concentration of the magnetic toner in the axial direction of the sleeve 2. Moreover, when the depth of the groove is <0.5mum, a function for flatening the carried magnetic toner can not be fulfilled.

Title: Production of sulfate ester salt of polyvinyl alcohol
Inventor: OURA MAKOTO
IPC: C08F8/42
Filed: 1993-02-10
Abstract: PURPOSE:To obtain a sulfate ester of polyvinyl alcohol having a high degree of esterification in high yield by sulfating PVA, removing the unreacted PVA, then treating the resultant product with an aqueous solution of an alkali and subsequently ultrafiltering the treated product. CONSTITUTION:PVA (preferably having 80-100% degree of saponification and 100-3000 degree of polymerization) is made to react with a sulfating agent (preferably pyridine salt of chlorosulfonic acid) and the unreacted PVA is then removed according to the filtration by suction using a glass filter. An aqueous solution of an alkali (preferably an aqueous solution of a strong alkali such as NaOH) is added to carry out the alkali treatment of the resultant PVA sulfate ester obtained as described above. The produced sulfate ester salt of the PVA is subsequently ultrafiltered and purified. Thereby, the objective compound is obtained.

Title: Chain for power transmission
Inventor: ODAI NOBUHIRO
IPC: F16G13/02
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To improve durability and a high-load resistant function by forming a groove or recess at least on one of the internal surface of a bus and the external surface of a pin for allowing the ingress of lubricating oil, and then specifying a difference between a bush inner diameter and pin outer diameter in an area except for the part of the groove or the recess. SOLUTION: An internal surface of a bush 2 is finished to be smooth, and a spiral groove 4A is formed on the external surface of a pin 4 over the entire length thereof. Thus, lubricating oil directly sprayed to a chain 1 from the outside or fed thereto via an oil pan enters the groove 4A and is reserved therein. Also, a difference between the inner diameter D of the bush 2 and the outer diameter (d) of the pin 4 is taken at a value between 0.05 and 0.6% of the pin outer diameter (d), so as to make small a difference between both. Consequently, an oil film across the bush 2 and the pin 4 becomes thin, but bearing pressure across contact surfaces due to the load of the chain 1 becomes small. At the same time, the lubricating oil is supplied across the bearing surfaces. As a result, the oil film is hardly exhausted, and proper lubrication state is maintained. According to this construction, durability becomes high, and resistance against a high load is ensured.

Filed: 1988-02-29
Abstract: PURPOSE:To eliminate the occurrence of uneven stripe by specifying the length of a projecting portion on the inner side of a developer container with respect to screw parts located within the effective developing width of a developing device. CONSTITUTION:For fixing machine screws 50 fixing a blade member 4, the length of the projecting portion L on the inner side of the developer container in each machine screw located within the effective developing width, are set at least in a range of 0-3mm. A smaller length of the projecting portion L is more effective, and by setting it <=3mm, it becomes good for the evenness of image without coagulation of developer around the projecting portion L. Particularly, in the developing device using one component magnetic toner with an average grain diameter of 3-8mum as developer, a length <=1mm is good as the length of the projecting portion L. Furthermore, by setting it <=0.5mm, the coagulation of the developer caused by the increased degree of coagulation can be prevented, and a high quality image free of image unevenness is obtained.

The casting W is in press-contact with the grinding ring body 2 with a press-contacting mechanism.  The grinding ring body 2 is formed with plural grinding ring bodies according to the shape of grinding surface of the casting W. By this method, the workability of the grinding can be improved and the working cost can be reduced.
